Application filed April 16, 1915. Serial No. 21,639.

To all whom it may concern:

Be it known that I, VICTOR \VILLOUGHBY, residing at Jeifersonville, Clark county, Indiana, and being a citizen of the United States, have invented certain new and use ful Improvements in Oilers for Mine-Car Wheels, of which the following is a full, clear, and exact description, such as will enable others skilled in theart towhich it appertains to make and to use the same, reference being had to the accompanying drawings, which illustrate the preferred form of the invention, though it 1s to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious'that various modifications thereof will occur to persons skilled in the art.

In said drawings: Figure 1 is a vertical sectional view through a mine car wheel equipped with the invention. Fig. 2 is a central vertical sectional view through the improved oiler. Fig. 3 is a transverse sectional view, the section being taken on line 33 of Fig. 2. Fig. l is a front elevational view, of the oiler.

The invention comprises means adapted to be associated with a mine car wheel for the purpose of lubricating said wheel on its axle and is intended to be associated with a lubricant chamber in a mine car wheel, which chamber is in communication with an axle bore in the hubi of the wheel in which position the device is operatively combined with the wheel upon which it is locked in position The object of the invention is to provide a self-contained oiling device which may be attached to wheels now inservice, as well as new wheels, and which may be readily removed for repairs or renewal of parts at any time.

Referring to the parts, 1 indicates generally a mine car wheel provided with the hub portion 2 through which extends an axle bore 3 connecting by means of the passages 4 with the lubricant chamber 5 into which extends the oiler indicated generally by the reference numeral 6. p

The oiler or lubricating device comprises features of novelty and utility which will be apparent from an inspection of the parts and comprises a valve cage 7 provided with an external screw thread 8 and open at both ends, the opening 9 at the inner end, as

shown in Fig. 3, being formed non-circular or rectangular in Fig. 3-for the reception of a non-circular tool which may be employedto rotate said valve cage to screw it in position inithe hub of the wheel or to remove it from such position when desired. 7

Mounted in the valve cage 7 is a valve10 having a frusto-conical head portion adapt ed to seatitse'lf in a suitable valve seat as 1l in the removable cap 12, said valve also being provided with: a stem portion 13 which, as shown in F ig. 2, extends through the non-circularopening 9, before indicated.

Within the valve cage is seated a spring 15 which bears against the inner face of the wall 16 'ofthe valve'cage at one end and against the base of the frusto-conical valve at its opposite end, thereby holding said valve normally in contact With its seat.

The removable cap 12 is screw-threaded, as best shown in Fig. 2, to adapt it for connection with the cage 7 and the cap may be removed without removing the cage, if

desired. It will be noted that the valve 10 projects slightly outside of or beyond the cap and is provided with a socketed outer end 20, which is adapted to receive the'end of the spout of an oil-can orother means by which the valve and its stem may be unseated and pushed into the cage far enough to permit insertion of the spoutcof an oilcan or other conduit for lubricant.

By reason of the frusto-conical shape of the valve, it is self-clearing and sediment which may be deposited on the projecting portion thereof may be wiped off before the valve is unseated, thereby preventing dust. and foreign matter passing from the exterior of the wheel into the oil cavity 5 and to the bearing for the axle. When the lubricator is positioned as illustrated in'Fig. 1, the valve cage extends withinthe lubricant chamber, the stem 13 of the valve projecting through the non-circular opening 9, the J valve projecting at thesame time through the cage, and the cap 12 serves as a jam nut to frictionally lock the device in position.

What I claim is: c

1. In combination, a screw-threaded cage. having an end Wall with a non-circular opening therein adapted to receive and cooperate with a non-circular tool to rotate said cage, said wall .forming a springseat, a coil spring bearing on said seat, a valve adapted tob'ear against the opposite end of said spring and a removable cap provided. with" a perforation adapted to serve as a valve seat'against which said valvemay be press'edbysaidspring. H i v 2. In an oiler, a cage open "at opposite ends, a removablefcap for one end of said cage, sprlng bearingon the opposite end of said cage and a valve.normallyiprojecting through saidcap and being provided.

, witharecess inits outerface.

3. In an oiler, a screw-threadedcage portion open at both ends, the inner. one of the openings being non-circular, wand being adapted to receive and cooperate with a non-circular tool to rotate saidcage, a valve in said cage adapted'to project through said non-circular opening,*a closure for the outer opening ofsaid cage, said closnre being formed with a valve seatand a spring bearing on saidcage and said lvalve;

Copies of this patent may be obtained for LlAn oiler for mine car wheels comprisinga valve cage formed with a non-circular opening through one end, which is adapted to receive and cooperate with a non-circular tool to rotate said cage, a removable closure for the other end comprising a valve-seat forming cap, a valve seated in said cap and a spring adapted to bear on said'valve'.

5. In combination in an oiler for mine car wheels a screw threaded valve cage having an inner end or bottom wall provided with a non-circular opening therein adapted to receive a non-circular tool which may be employed to rotatesaid valve cage to screw it in position in the hub of a wheel, a coil spring bearing on said wall, a valve bearing against the opposite end of said spring and a removable perforated cap cooperating with said screw thread to lock the valve cage in position in a wheel.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
